STOVE.

SPECIFICATION formingpart of Letters Patent No. 738,974, dated September 15, 1903.. Application filed January 9, 1903. $erial No. 138 ,331. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM BELL, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

My invention relates to improvements in stoves.

It consists of a suitably-perforated metallic tube or hollow pipe, the object of which is to supply oxygen for the combustion of gases, smoke, or carbon set freein the burning of fuel in the fire-pot of a stove. I attain this object by the construction and use of a perforated metallic tube, shown and illustrated in the accompanying drawings, in which-- Figure 1 represents a side view of the perforated metallic tube in place in the fire-pot of a stove.

Fig. 2 represents a perspective side view of the perforated metallic tube. Fig. 3 represents a perspective end view of the upper end of the perforated metallic tube.

Ordinarily a large amount of gas, smoke, and carbon fails of combustion and escapes from many heatingstoves burning either hard or soft coal or slack, and the gas, smoke, and soot escape from the openings in the stove and into the room, often causing injury and discomfiture to persons in the room at the time. This failure of complete combustion of the gas, smoke, or carbon is due to an in sufficient quantity of oxygen in and over the fire-pot of the stove while the fuel is being burned.

In the accompanying drawings, a a represent the perforated metallic tube; 1) Z), the horizontal opening or hollow part of the tube c, the hook at the upper end of the tube; d, the aperture in the wall of the fire-pot; e,the grate in the bottom of the fire-pot; f, the fire-pot, and g the perforations in the metallic tube.

My invention consists of a suitable metallic tube or hollow pipe of any convenient lengthsay, twelve inches long'and'of any convenient diameter, ordinarily about an inch and a half in diameter, with a hook mounted on one side by which it may be fastened to the wall of the fire-pot, and is further held in place by the coal or other fuel surrounding it in the firepot. This metallic perforated tube 1) bis placed in the fire-pot of an ordinary heatingstove and set vertically in the fire-pot f, the lower end of the tube resting on the firegrate e, the hook c inserted in the aperture or opening bin the wall of the fire-potf. The perforated metallic tube is of such length as to project to the upper edge of the fuel in the fire-pot. This tube has a number of perforations of short diameters, which are represented by the letter 9, and the oxygen for combustion of the gas, smoke, and carbon accumulating in the fire-pot is freely supplied by a current of air which passes into the metallic tube at its lower end, and also through the perforations, and the current of air rises in the hollow space in the tube and produces complete combustion of the gases, carbon, and smoke in the tube and over the fuel in the fire-pot of the stove.

It is obvious that the construction herein described admits of various modifications, and it is not my intention to limit my invention to the exact construction herein described and illustrated, for I have illustrated only a simple form of tube and arrangement of parts, and they may be varied in any desired manner, so as'to accomplish the results herein described, without departing from the spirit of my invention.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. In combination with a stove having an opening in the forward part of the fire-pot near the top thereof, of a perforated metallic tube, substantially the same length as the depth of the fire-pot, and a hook formed-integral with the tube near the top thereof adapted to enter the opening in the fire-pot.

2. In combination with a stove having an opening in the forward part of the fire-pot, of a device of this character comprising a cylindrical perforated tube adapted to have its lower end rest upon the grate and its upperv end project above the fire-pot, and a hook formed integral with the tube upon one side thereof adapted to enter the opening of the fire-pot and be supported thereby.

In testimony whereof I affix my signature in presence of two witnesses.

WVILLIAM BELL.
